Book 2, Number 2.8.42: Yahya related to me from Malik from Ibn Shihab from Abbad ibn Ziyad, a descendant of al−Mughira ibn Shuba from his father from al Mughira ibn Shuba that the Messenger of Allah, may Allah bless him and grant him peace, went to relieve himself during the expedition of Tabuk. Mughira said, "I went with him, taking water. Then the Messenger of Allah, may Allah bless him and grant him peace, came back and I poured out the water for him. He washed his hands and then went to push his hands out of the sleeves of his garment, but could not do so because of their narrowness. So he brought them out from underneath his garment. Then he washed his arms, wiped his head and wiped over his leather socks. The Messenger of Allah, may Allah bless him and grant him peace, returned and Abdar Rahman ibn Awf was leading the people in prayer, and he had already finished one raka with them. The Messenger of Allah, may Allah bless him and grant him peace, prayed the remaining raka with them to everyone's concern. When the Messenger of Allah, may Allah bless him and grant him peace, finished he said, 'You have acted correctly.'"
Book 2, Number 2.8.43: Yahya related to me from Malik that Nafi and Abdullah ibn Dinar told him that Abdullah ibn Umar arrived at Kufa and went to Sad ibn Abi Waqqas, who was the Amir of Kufa at that time. Abdullah ibn Umar saw him wiping over his leather socks and disapproved of it. So Sad said to him, "Ask your father when you get back." Abdullah returned but forgot to ask Umar about the matter until Sad arrived and said, "Have you asked your father?" and he said, "No." Abdullah then asked Umar and Umar replied, "If your feet are ritually pure when you put them in the leather socks then you can wipe over the socks." Abdullah said ,"What about if we have just come from relieving ourselves?" Umar said, "Yes, even if you have just come from relieving yourself."
Book 2, Number 2.8.44: Yahya related to me from Malik from Nafi that Abdullah ibn Umar urinated in the market place and then did wudu, washing his face and hands and wiping his head.
Then as soon as he had come into the mosque, he was called to pray over a dead person, so he wiped over his leather socks and prayed.
Book 2, Number 2.8.45: Yahya related to me from Malik that Said ibn Abd ar−Rahman ibn Ruqash said, "I saw Anas ibn Malik come and squat and urinate.Then water was brought and he did wudu. He washed his face, then his arms to the elbows, and then he wiped his head and wiped over his leather socks. Then he came to the mosque and prayed." Yahya said that Malik was asked whether a man who did wudu for prayerand then put on his leather socks, and then urinated and took them off and put them back on again, should begin wudu afresh. Malik replied,
"He should take off his socks and wash his feet. Only someone who puts on leather socks when his feet are (already) ritually purified by wudu can wipe over them. Someone who puts on leather socks when his feet are not ritually purified by wudu, should not wipe over them." Yahya said that Malik was asked about a man who did wudu with his leather socks on and forgot to wipe over them until the water was dry and he had prayed, and he said, "He should wipe over his socks and repeat the prayer but not repeat wudu." Malik was asked about a man who washed his feet and put on his leather socks and then started doing wudu, and he said, "He should take off his socks and do wudu and wash his feet."
